What are the best Linux native ports?

I've never been a "no tux no bux" person, but I have to admit that I am a little worried about possible over-reliance on Proton in the years ahead.

I'd like to support more Linux native games, but so many of them have ports so awful that there's no reason not to use WINE anyway. Whether they be actually broken, slow due to OpenGL, or just generally wonky...there's a lot of shitty ports out there. So I'm curious: what ones are particularly polished or impressive?
